Ozokerite

Ozokerite or ozocerite, archaically referred to as earthwax or earth wax, is a naturally occurring odoriferous mineral wax or paraffin found in many localities. Lacking a definite composition and crystalline structure, it is not considered a mineral but only a mineraloid. The name was coined from Greek elements Όζω ozο, to stink, and κηρός keros, wax.
